Let's share interesting locations on Earth.

This is Crater Lake in Oregon. This was once a volcano that erupted forming a caldera lake within the collapsed remains.

Here is an aerial view.

Penitentes are thin blades or spires of snow and ice that form in high altitudes.

This is an entire field full of them.

Pingualuit Crater is an impact crater located on the Ungava Peninsula in Quebec, Canada.

The crater was formed by a meteorite impact from about 1.4 million years ago.

Within the crater is a lake that hold some of the purest fresh water in the world without any inlets or outlets. Water accumulates from only rain and snow.

Sistema Dos Ojos is a flooded cave system located in Quintana Roo, Mexico.

At this time it has been surveyed to be 51 miles with 28 known sinkholes entrances but the investigation continues.

Craters formed from meteors hitting the earth. Goes along with their giant folklore and fairies somehow, but I don't remember exactly.

The eruption of Novarupta is one of the largest volcanic eruptions of the 20th century releasing 30 times the volume of magma of Mount St. Helens.

Here is a picture of Novarupta's lava dome.

Białowieża Forest located between the borders of Hrodna and Brest Voblasts, Belarus and Podlaskie Voivodeship, Poland.

This forest is one of the last and largest remaining parts of an immense primeval forest that once stretched across the European Plain.

Lake Untersee is a surface freshwater lake hidden in the interior of the Gruber Mountains of central Queen Maud Land in East Antartica.

The lake is 4 miles long and 1.6 miles wide with a maximum depth of 554 feet and is permanently covered with ice and partially bounded by glacier ice.

It has a pH between 9.8 and 12.1. In the past the water chemistry has been compared to Clorox.

The Bingham Canyon Mine is the largest man-made excavation in the world.

This open-pit mine was opened in 1906 and still operates to this day although the current mine plan is set to expire in 2019.

(http://s.w-x.co/81fd089c-2d03-4adf-9b5f-debf9666819e.jpg)

The mine extracts copper, gold, silver, and molybdenum.

(https://img1.hobbyearth.com/xxlarge/container_tile_cover/565ec9eec981e.jpg)

Here is an image of the mine in 1907.

(https://upload.wikimedia.org/wikipedia/commons/d/d9/Panorama_of_Bingham_Canyon_Mine_in_1907.png)

Environmentally there have been several chemical spills between 2000-2014 among other problems - but that isn't what we're here for. To say the least there seems to be a big groundwater problem due to mining activities.
